METHOD OF GENERATING OPTIMAL CONTROL PROBLEMS FOR INDUSTRIAL PROCESSES

摘要

The invention simplifies the use of the Mixed Logical Dynamic (MLD) framework for modelling of industrial processes and allows to automatically generate and solve optimal control problems and scheduling applications for said industrial processes. A core technical aspect of the invention is the automatic merging of two arbitrarily connected MLD blocks to obtain one composite MLD block. Via a repeated use of the procedure, any arbitrarily complex system containing the complete description of an industrial process can be generated from the simplest MLD building blocks. The optimal control problem is generated via adding an MLD block whose unique output becomes the cost functional of the problem. In a graphical environment, any specific industrial process may be reproduced by instantiating blocks from a library of basic MLD elements or atomic MLD blocks and by properly connecting them. In case an appropriate library is available, this process will not require any expert knowledge from the end user apart from the ability to build the graphical interconnections mentioned.
